ZOTAC RTX 5080 16GB Apocalypse OC graphics card

Apocalypse OC RTX 5080 16GB

The ZOTAC Apocalypse OC GeForce RTX 5080 is a 16GB GDDR7 graphics card built for 4K gaming and professional rendering. It targets enthusiasts who need high frame rates in modern titles and compute throughput for AI workloads. The Blackwell architecture provides 10752 CUDA cores and a 2617 MHz boost clock. Factory overclocking pushes the core to 2730 MHz out of the box.

PCI Express 5.0 x16 interface limits

The card uses a PCI Express 5.0 x16 slot for maximum host bandwidth. A 12V-2x6 power connector supplies the 360W board power, while an 800W power supply is recommended for the full system. Three DisplayPort 2.1b outputs and one HDMI 2.1b port drive up to four displays at 15360×8460 resolution. The 3.5-slot cooler occupies significant case space and requires 361mm length clearance.

16GB GDDR7 on a 256-bit bus

Memory capacity and bus width decide if this model fits a workload. The 16GB frame buffer and 256-bit interface deliver 30 Gbps effective speed for texture-heavy 4K scenes and large model inference. Less VRAM would bottleneck high-resolution assets; a wider bus is not available on this GPU. Buyers should match the 16GB specification to their target resolution and dataset size.
